|Redwood tree (Sequoideae)|
These trees are pyrophytes, which means they have adapted to protect themselves from fire. Because fire is common in the regions where they grow, redwood trees have developed thick, fire-resistant bark. Their cones open only after a fire. Due to better fire control in modern times, these trees are endangered.
Redwood trees can grow to be very large. The largest species, Sequoiadendron giganteum, can reach up to 94.8 m tall and 17 m across. The tallest tree in the world is a Sequoia sempervirens named Hyperion. The largest tree in the world by volume is a Sequoiadendron giganteum named the General Sherman Tree, after William Tecumseh Sherman.
